Web根據Fe-Fe3C相圖可以確定合金的澆注溫度。 澆注溫度一般在液相線以上50℃~100℃。 從相圖上可看出,純鐵和共晶白口鑄鐵的鑄造性能最好,它們的凝固溫度區間最小,因而流動性好,分散縮孔少,可以獲得緻密的鑄件,所以鑄鐵在生產上總是選在共晶成分附近。 Web铁碳相图基础篇 Fe-C合金相图实际上是Fe-Fe3C相图,铁碳合金的基本组元也应该是纯铁和Fe3C。 铁碳合金相图是研究铁碳合金的工具,是研究碳钢和铸铁成分、温度、组织和性 …
Web因为Fe3C是亚稳相,在一定条件下可以分解为铁和石墨,因此铁碳相图可有两种形式:Fe-Fe3C相图和Fe-C(石墨)相图。为了便于比较和应用,通常将两者画在一起,称为铁碳双重相图。一般用实线表示Fe-Fe3C相图,虚线表示Fe-C(石墨)相图,当虚线与实线重合时则用实线 ... http://www.cailiaoniu.com/202443.html
