The results of XRD analysis showed that the enhanced activity of heat-treated catalysts appeared to originate primarily as a result of the change in the lattice structure.
XRD分析的结果表明，热处理催化剂活性的提高看来主要是由晶格结构改变的结果引起的。

The research describes the formation of Widmanstatten structure and martensite in iron-carbon alloys possessing a broad range of carbon contents and heattreated using a broad range of cooling rates.
Adding copper into nodular iron caused change of its structure and properties both in as - cast as well as heat - treated condition that expanded application scope of nodular iron.
