The above mentioned powder metallurgy sintered preform with constant initial theoretical density of 84% of different aspect ratios, namely, 04 and 06 respectively were prepared using a suitable die-set assembly on a 1 MN capacity hydraulic press and sintered for 90 min at 1200 ℃. Each sintered preform was cold upset under nil/no and graphite frictional constraint, respectively. Under the condition of triaxial stress densification state, axial stress, hoop stress, hydrostatic stress, effective stress and formability stress index against axial strain relationship was established and presented in this work. Further more, attained density was considered to establish formability stress index and various stress ratio parameters behaviour.","authors":[{"authorName":"S Narayan","id":"5cdb6c50-de5c-4aca-9276-c1ef2357381d","originalAuthorName":"S Narayan"},{"authorName":"A Rajeshkannan","id":"d94d8198-3166-4531-8777-401f156cd20c","originalAuthorName":"A Rajeshkannan"}],"categoryName":"|","doi":"","fpage":"71","id":"59bdecfd-f500-4b22-b3cf-f1ca4426ca61","issue":"12","journal":{"abbrevTitle":"GTYJXBYWB","coverImgSrc":"journal/img/cover/GTYJXBEN.jpg","id":"1","issnPpub":"1006-706X","publisherId":"GTYJXBYWB","title":"钢铁研究学报(英文版)"},"keywords":[{"id":"904233c5-d32c-4192-bef6-1a3690db01b2","keyword":"powder metallurgy ","originalKeyword":"powder metallurgy "},{"id":"454f5117-c793-419f-ba78-03c2b3e5ae10","keyword":" failure analysis ","originalKeyword":" failure analysis "},{"id":"6f52f83a-8db9-4b40-9710-e876ddbe287f","keyword":" plastic behaviour ","originalKeyword":" plastic behaviour "},{"id":"6009bf1f-3f06-40af-9404-b5768d3238c1","keyword":" workability","originalKeyword":" workability"}],"language":"en","publisherId":"1006-706X_2011_12_5","title":"Workability Studies in Forming of Sintered Fe-035C Powder Metallurgy Preform During Cold Upsetting","volume":"18","year":"2011"},{"abstractinfo":"A siliconizing process to manufacture 6.5% Si steel sheet has been developed. Electric components. such as transformers and reactors are made easily from 6.5% Si steel sheet. However, improved workability is desirable to increase the applications. Therefore the improvement of workability of 6.5% Si steel sheet was investigated, and the results were obtained as follows: (a) workability of 6.5% Si steel sheet is deteriorated by grain boundary oxidization, (b) grain boundary oxidization can be restrained by the addition of C. Workability and magnetic properties of 6.5% Si steel sheet with C addition are discussed. Furthermore, it was found that the workability of high Si steel sheet was improved remarkably by varying the Si content gradient along the thickness without deterioration of high frequency magnetic properties. This newly developed magnetic gradient high Si steel sheet is also discussed.","authors":[{"authorName":"Koichiro Fujita","id":"864f58d4-fa8c-449c-86ed-f95c10447d04","originalAuthorName":"Koichiro Fujita"},{"authorName":" Misao Namikawa","id":"72c8a4b4-d40f-4e6a-bd72-8f476368de72","originalAuthorName":" Misao Namikawa"},{"authorName":" Yoshikazu Takada","id":"e02fbba5-b221-4362-ae92-3162b081447b","originalAuthorName":" Yoshikazu Takada"}],"categoryName":"|","doi":"","fpage":"137","id":"c3750c46-f99c-4b4d-b5a8-60cf77641385","issue":"2","journal":{"abbrevTitle":"CLKXJSY","coverImgSrc":"journal/img/cover/JMST.jpg","id":"11","issnPpub":"1005-0302 ","publisherId":"CLKXJSY","title":"材料科学技术(英文)"},"keywords":[],"language":"en","publisherId":"1005-0302_2000_2_46","title":"Magnetic properties and workability of 6.5% Si steel sheet manufactured by siliconizing process","volume":"16","year":"2000"},{"abstractinfo":"The influence of 001% to 025% of Aluminum content (in mass percent) on the mechanical properties and cold workability of low thermal expansion Fe-33Ni-15Co sheets in the annealed and hot rolled condition was investigated.

Besides, achievement of fine grain structure and increase in the amount of annealing twins caused ductility to improve. Addition of Al higher than 015% led to the increase in oxidation reaction during melting process and to refine under argon atmosphere. This caused the volume fraction of Al containing inclusions to increase and consequently the ductility and toughness to decrease.","authors":[{"authorName":"M Safavi","id":"88e8876b-95ca-44f0-bda1-6fafd9b7ac7e","originalAuthorName":"M Safavi"},{"authorName":"S M Abbasi","id":"a105faa5-a212-4f23-837e-85f806eef664","originalAuthorName":"S M Abbasi"},{"authorName":"R Mahdavi","id":"20329d29-2ab9-44dc-81d5-d01d518ed0d5","originalAuthorName":"R Mahdavi"}],"categoryName":"|","doi":"","fpage":"67","id":"2d2c5c4c-3482-4f7a-9e68-355b09f51f41","issue":"2","journal":{"abbrevTitle":"GTYJXBYWB","coverImgSrc":"journal/img/cover/GTYJXBEN.jpg","id":"1","issnPpub":"1006-706X","publisherId":"GTYJXBYWB","title":"钢铁研究学报(英文版)"},"keywords":[{"id":"4add4837-f829-48fd-a27b-1f2c0307449b","keyword":"Fe-33Ni-15Co alloy ","originalKeyword":"Fe-33Ni-15Co alloy "},{"id":"f48f5095-27a4-4c27-a55b-da4610502f14","keyword":" Al content ","originalKeyword":" Al content "},{"id":"1415f217-51ec-4622-b9a1-f4444c61e436","keyword":" mechanical property ","originalKeyword":" mechanical property "},{"id":"ffa28d3c-5f9c-4282-8ee6-e435b5746daf","keyword":" cold workability","originalKeyword":" cold workability"}],"language":"en","publisherId":"1006-706X_2012_2_10","title":"Influence of Aluminum Content on Mechanical Properties and Cold Workability of Fe-33Ni-15Co Alloy","volume":"19","year":"2012"},{"abstractinfo":"The effect of processing parameters on hot workability and microstructure evolution during subtransus deformation of TC11 alloy with widmanstaten microstructure was studied using isothermal compression tests. Testing was conducted at strain rates of 0.1-10s(-1), temperature ranges 920-980 degrees C and height reductions of 30-70%. The influence of hot working parameters on flow behavior, hot workability and microstructure evolution was systemically investigated. The results showed that all the flow curves exhibited a peak stress at very low strains (<0.1) followed by extensive flow softening. Surface fracture, cavitations and localized shear flow were found to be main factors that limited the hot workability of TC11 alloy. At low strains, lamellar kinking started to occur due to the orientation between the colony alpha lamellar and stress axis. With deformation continues, reorientation of the lamellar colony occurred and the deformed lamellar became elongated and thinner. At high stains, segmentation and globularization of alpha lamellar took place to produce a refined microstructure with alpha grain size around 1 mu m that is technologically desirable for secondary processes such as superplastic forming. A microstructure mechanism map based on the previous results was then established and applied to process design considering defect and microstructure control.","authors":[],"categoryName":"|","doi":"","fpage":"875","id":"ba140e09-777b-40bc-b100-fd7ba23edbc3","issue":"42893","journal":{"abbrevTitle":"IJOMPB","id":"8ecc85e1-d03b-4838-9406-aa241f502c59","issnPpub":"0217-9792","publisherId":"IJOMPB","title":"International Journal of Modern Physics B"},"keywords":[{"id":"d7a5e801-6b6d-4a2a-9974-cd2ad1667903","keyword":"TC11 alloy;flow behavior;hot workability;microstructure evolution;globularization;starting structure;ti-6al-4v;evolution;behavior;working","originalKeyword":"TC11 alloy;flow behavior;hot workability;microstructure evolution;globularization;starting structure;ti-6al-4v;evolution;behavior;working"}],"language":"en","publisherId":"0217-9792_2009_42893_5","title":"HOT WORKABILITY DURING SUBTRANSUS DEFORMATION AT HIGHER STRAIN RATES OF TC11 ALLOY WITH WIDMANSTATTEN MICROSTRUCTURE","volume":"23","year":"2009"},{"abstractinfo":"Constitutive flow behavior and hot workability of the powder metallurgy processed 20 vol.%SiC(P)/2024Al composite were investigated using hot compression tests. The modified Arrhenius-type constitutive equations were presented with the values of material constants in consideration as a function of strain. Dynamic material model (DMM) and modified DMM were used to construct the power dissipation efficiency maps, and Ziegler's instability criterion and Gegel's stability criterion were used to build instability maps. The presence of finer SiC(P) and more boundaries resulting from smaller 2024Al powders shifted the dynamic recrystallization domain of the 2024Al matrix to higher strain rate and lower temperature ranges and decreased the peak value of power dissipation efficiency. Large instable regions were found in the form of flow localization and cavitations located at the matrix/SiC(P) interfaces and within the SiC(P) clusters. By comparison, the Gegel's stability criterion was more sensitive to the instability zones than the Ziegler's instability criterion for this material. (c) 2010 Elsevier B.V.
