The microstructure, strength-toughness and fatigue properties of an ultrahigh strength steel 40CrMnSiMoVA have been investigated. The so-called eta-bainite,composed of thin rareined austenite films within or between the bainitic ferrite laths was found in the steel after isothermally quenched at 300℃ for 1h.

本文研究了飞机起落架用超高强度40CrMnSiMoVA钢的显微组织、强韧性和疲劳性能，结果表明，该钢经300℃等温1h淬火可获得由贝氏体铁素体板条与条间或条内的残余奥氏体薄膜所组成的准贝民体组织。

Numerical controlled program was compiled with ETA code. The baffles were welded into a pile, then the holes were drilled using milling cutter and twist drill. The baffles were installed on Mitsubishi numerical controlled machine, and numerical controlled process was realized. This can improve production efficiency, which makes it possible that helix-baffled tubular heat exchangers can be widely applied in factory.

在MITSUBISHI操作系统的数控钻铣床上，采用特殊的刀具，将折流板点焊为一擦，装夹在旋转工作台上，使之与刀具成一个固定角度，实现了阶梯式螺旋折流板上孔的加工，解决了制造的难题，提高了生产效率和钻孔精度，为螺旋折流板管壳式换热器的推广应用提供了可能。
