Bainite
History
In the 1920s Davenport and Bain discovered a new steel microstructure which they provisionally called martensite-troostite, due to it being intermediate between the already known low-temperature martensite phase and what was then known as troostite (now fine-pearlite).

波来铁
当冷却速率较慢,例如放置在炉中冷却时,生成的肥粒铁和雪明碳铁组织较粗,因此称为粗波来铁;放置于空气中冷却时,由于冷却速率较炉冷快,生成的波来铁组织较细,称为中等波来铁或糙斑铁(sorbite);而在油中冷却时,冷却速率更快,生成的波来铁组织更细,就称为细波来铁或吐粒散铁(troostite)。

– small distinct crystalline particles due to martensite, austenite, pearlite or troostite that appear like twinkling stars. – indistinguishable crystalline particles due to martensite, austenite, pearlite or troostite that appear together like a wash of stars.
