angular process 隅骨突起。

angularity

In performing ecap , a material is subjected to intense plastic straining by pressing a sample repeatedly through a die containing two channels , with equal cross - sections , intersecting at an angle . equal channel angular processing of the medium carbon steel ( 0 . 45 wt . % Ecap變形是使試樣通過橫截面相等并成一定交角的兩通道的模具中而產生強烈的塑性變形的一種變形方法。最近人們運用ecap變形方法成功地使低碳鋼及珠光體鋼組織超細化,關于這方面的研究已引起了人們的廣泛關注。

Equal channel angular processing of the pearlitic steel ( 0 . 65 wt . % c ) was successfully carried out at 650 with route c in this study , obtaining a total equivalent true strain ~ 5 . the microstructure evolution of pearlitic steel in ecap was investigated by means of transmission electron microscope and scanning electron microscope . the main results are as the following : 1 本研究成功地實現了c方式650珠光體鋼65mnecap變形,累積等效真應變達到5 。并用透射電鏡、掃描電鏡研究了珠光體組織的演變特點和滲碳體的變形。主要結果如下: 1

Severe plastic deformation ( spd ) processing , especially equal - channel angular processing ( ecap ) of steel and other iron - based alloys , has achieved increasing interest recently because of the potential for obtaining ultrafine grains and improving the properties 近年來,強烈塑性變形特別是鋼和鐵基合金的等徑彎曲通道變形因為具有獲得超細晶組織和改善性能的潛力,引起了各國研究人員的很大興趣。

Paratype 1 , same date . this species is very similar to a . incwata , but differ in pygofer process with two asymmetrical angular process near apex and the markings of pronotum is also different . 2 使用相關指令得到參數值相同的2個樹,通過比較樹1接受為本亞科的系統發育圖,并對其進行分析,同時輸出它的性狀參數值。
