材料科学技术（英文）

The crystallization behavior and crystallization kinetics of (Cu60Zr30Ti10)99Sn1 bulk metallic glass was studied by X-ray diffractometry and differential scanning calorimetry. It was found that a two-stage crystallization took place during continuous heating of the bulk metallic glass. Both the glas...

Carbide Behavior during High Temperature Creep in DZ40M Co-base Superalloy

Wenhui JIANG , Xiangdong YAO , Hengrong GUAN , Zhuangqi HU

材料科学技术（英文）

The carbide behavior of a directionally solidified Co-base superalloy DZ40M has been investigated after creep at 700 and 900℃. During the high temperature creep, a great amount of secondary carbide, M23C6 precipitated in alloy matrix. At 700℃, the M23C6 precipitation occurred in slip bands, indicati...
