深入研究了合金Sm3Fe18.5Co9Ti1.5的HD和HDDR处理过程。HD过程分别于350、400和450℃处理4h;HDDR过程于800℃处理2h。试验发现HD和HDDR法均可有效的对合金进行破碎处理,HDDR法由于其形核长大机制可有效的用于制备纳米晶复合材料;350℃时HD法可以有效的进行,随着温度的升高试样发生分解反应。给出了HD及HDDR处理后合金所表现的典型形貌。
In-depth study of the alloy Sm3Fe18.5Co9Ti1.5 HD and HDDR processing. The HD process was performed at 350, 400 and 450 ° C for 4 h, respectively; the HDDR process was performed at 800 ° C for 2 h. It was found that the HD and HDDR methods can effectively crush the alloy. The HDDR method can be effectively used to prepare nanocrystalline composite materials due to its nucleation and growth mechanism. The HD method can be effectively performed at 350 ° C. With the increase of temperature Increase the sample decomposition reaction. The typical morphologies of HD and HDDR treated alloys are given.
