本文介绍了几种常用焊缝金属和熔化的21/4Cγ—1Mo基本金属在冷却过程中的相交温度在直接凝固之后用热分析方法,而在热循环过程中用热分析和膨胀两种方法,测定了固态下的转变。凝固后冷却速度的影响,热循中。为了应用热分析测环过程中加热速度和冷却速度的影响,都体现在转变行为定转变温度,发展了一种新技术,叫做“液体熔滴技术”。 This article describes the thermal analysis of several common weld metal and melting 21 / 4Cγ-1Mo base metals in the cooling process after the direct solidification temperature, and in the thermal cycle process with thermal analysis and expansion of two methods, The change in solid state was measured. Effect of cooling rate after solidification, thermal cycling. In order to apply the effect of heating rate and cooling rate in the thermal analysis loop, all of them are reflected in the transition temperature and the development of a new technology called “liquid droplet technology.”
