A well known vapour case is the snowflake. Most liquid metal products solidify by forming dendrites. Crystal growth from an already crystalline matrix is also found to produce precipitates with a dendritic morphology. However, dendritic precipitates were scarcely observed to form from liquid state. In the present paper, a directionally solidified <span style=\"color:red\">nickel</span> <span style=\"color:red\">based</span> superalloy was designed to show the dendritic growth of precipitates from the liquid state. The formation of carbides led to the negative temperature gradient and constitutional supercooling in the residual liquid melts as a result of the release of latent heat and ejecting of forming precipitate elements respectively. This resulted in the formation of dendritic primary precipitates.","authors":[],"categoryName":"|","doi":"","fpage":"83","id":"e9c99170-3db6-4732-8055-b323b0848007","issue":"1","journal":{"abbrevTitle":"MSAT","id":"5c4ea523-f3ab-4618-9c21-537efff1d7fc","issnPpub":"0267-0836","publisherId":"MSAT","title":"Materials Science and Technology"},"keywords":[{"id":"6a321e44-138f-4827-9993-6d05b85b9fef","keyword":"<span style=\"color:red\">Nickel</span> <span style=\"color:red\">based</span> superalloy;Precipitate;Dendrite;superalloy","originalKeyword":"Nickel based superalloy;Precipitate;Dendrite;superalloy"}],"language":"en","publisherId":"0267-0836_2012_1_1","title":"Dendritic growth of primary gamma ' precipitates in <span style=\"color:red\">nickel</span> <span style=\"color:red\">based</span> <span style=\"color:red\">alloy</span>","volume":"28","year":"2012"},{"abstractinfo":"采用特制高压釜设备，研究304L不锈钢、316L不锈钢、317L不锈钢和镍基合金（Incoloy 800）在高温高压醋酸溶液中的腐蚀，初步探讨了不锈钢和镍基合金在醋酸溶液中的腐蚀机理及Ni和Mo元素对提高不锈钢耐蚀性能的影响。结果表明，温度对不锈钢和镍基合金耐蚀性有显著影响，随着温度的升高，腐蚀速率逐渐增大，当温度升高到一定值，不锈钢的耐蚀性会急剧下降。在低温醋酸溶液中，Ni对于提高不锈钢耐蚀性是有益的；在高温醋酸溶液中，Ni对于提高不锈钢耐蚀性没有显著影响。在低温醋酸溶液中，Mo对于提高不锈钢耐蚀性没有显著影响；在高温醋酸溶液中，Mo对于提高不锈钢耐蚀性是有益的。","authors":[{"authorName":"程学群","id":"f7505fd9-c161-4add-bf99-fa80228364b7","originalAuthorName":"程学群"},{"authorName":"李晓刚","id":"e7138e8f-51e1-40c2-b260-0be59d809968","originalAuthorName":"李晓刚"},{"authorName":"杜翠薇","id":"db4d360e-47ef-410a-87ac-b4936c8683af","originalAuthorName":"杜翠薇"}],"categoryName":"|","doi":"","fpage":"70","id":"52c1e918-f3c9-4f84-b05c-d4a20e97f04d","issue":"2","journal":{"abbrevTitle":"ZGFSYFHXB","coverImgSrc":"journal/img/cover/中国腐蚀封面19-3期-01.jpg","id":"81","issnPpub":"1005-4537","publisherId":"ZGFSYFHXB","title":"中国腐蚀与防护学报"},"keywords":[{"id":"5a18f765-815c-4ae8-b773-edbc12f39a8c","keyword":"醋酸","originalKeyword":"醋酸"},{"id":"40e4000e-72b9-4245-bc82-4762b42a4569","keyword":"Stainless steel","originalKeyword":"Stainless steel"},{"id":"b184c3c9-106b-4258-afbc-be0d8125534f","keyword":"<span style=\"color:red\">Nickel</span> <span style=\"color:red\">Based</span> <span style=\"color:red\">Alloy</span>","originalKeyword":"Nickel Based Alloy"},{"id":"90755e63-e6d5-4515-8df3-bb2a9b0eda91","keyword":"Corrosion","originalKeyword":"Corrosion"}],"language":"zh","publisherId":"1005-4537_2006_2_1","title":"不锈钢和镍基合金在高温高压醋酸溶液中的腐蚀行为","volume":"26","year":"2006"},{"abstractinfo":"Effect of stoichiometry on microstructures, electrochemical properties and PCT characteristics of the alloys Ml(Ni0.71Co0.15-Al0.06Mn0.08)x (Ml=Lanthanum-rich Michmetal, x=4.6-5.2) have been investigated.
