hot hardness,red hardness是什么意思

用法例句

Study on New Thermosetting Inorganic Resin Binder for Moulds and Cores;

一种新的环保型热硬化无机高聚物铸造粘结剂研究

The results show that the RE-Al-bronized layer may be consisted of phases FeB without (Fe,Al)B or (Fe,Al)_2B,and the microstructure of the layer is continuous and compact, the layer possess high microhardness and red hardness.

结果表明,共渗层主要由FeB相构成,没有发现(Fe,Al)B或(Fe,Al)2B物相;共渗层组织连续致密,具有很高的显微硬度和热硬性。

By using such process, the hardness, together with the red hardness of the steel, may be increased evidently.

这种工艺能在显著提高钢的硬度和热硬性的同时,兼有易于操作和节约能源的优点。
