at room temperature, and microvoid coalescence fracture at 250-300 ℃. Key words: magnesium alloy; rare earth; aging treatment; tensile property aging treatment. The isothermal aging tests were taken to evaluate the response of alloy to precipitation hardening during aging treatment. The results were measured by changing......
field, including temperature, time and applied magnetic field. There are optimized isothermal aging temperature and time in different magnetic heat treatment conditions. High magnetic field strength...Study on Thermomagnetic Treatment Fe-25.5Cr-12Co Permanent Magnetic Alloy Zhen Liang1,GAO Run-sheng2,ZHU Dan-yang1,SUN Xue-yin1,SHAO Wen-zhu1,XU Ren-gen1 (1.Technology and Development Centre......
greater than that of the 7075-T6 alloy. Compared with T6 treatment, the RRA, T73, T6I6 and HTPP aging treatments cause the discontinuous distribution of the h precipitates at the grain boundary..., but the studied HTPP aging and T73 treatments lower its strength. Key words: 7075 Al alloy; aging treatment; tensile property; corrosion behavior; microstructure ......
]. These mechanical properties can be changed significantly through microstructural control by processing as well as heat treatment variations [2-3]. A problem often encountered in the aging treatment... aging treatment must be evaluated in order to make accurate estimations of component life or to guide the alloy designer in improvement of alloy composition. Ti-5Al-5Mo-5V-1Cr-1Fe alloy is a deeply......

-aging treatment was used in order to gain relative stable structure. Several investigations regarding the aging characteristics of hypo-eutectic and hyper-eutectic Zn-Al alloys have been performed using... and preci- pitation phases in both materials after aging treatment were observed using SEM (HITACHI X-650) at the accelerating voltage of 20 kV, EDS (attached to the SEM) and TEM (JEM-2000EX......
