al [10] studied the effect of NaOH solution treatment on the phase transformation and morphology of calcium phosphate, and found that calcium phosphate deposit could be converted into HA phase by NaOH...- chloric acid solution. After deposition, the sample was washed with distilled water, and then air-dried. To study the alkaline treatment process of calcium phosphates, the coated sample......
Computer Aided Design of Heat Treatment for AISI P20+Ni Mold Steel with Good Machinability HU Xin-bin1,GAO Wen3,HE Yan-lin1,LI Lin1 (1.Dept. Mater. Sci. & Eng., Shanghai University, 149 Yanchang...:Computer aided design of heat treatment for AISI P20 mold steel with good machinability is attempted to proceed by the commercial software package Thermo-Calc (TCP+DICTRA).

treatment for large number of β-Mg17Al12 phase precipitated discontinuously at the grain boundaries notwithstanding the grains are fined a little. Key words: AE42 alloy; indentation creep; microstructure... diffractometry (XRD). The results reveal that the steady creep rates and primary indentation deformation of AE42 alloy increase with increasing temperature and stress. The average stress exponent......
