Critical operating temperature can be determined for the machine components that form key functional part of device. This article describes a change failure mechanism in material an engine, where structure consists fine pearlite layers with lamellar graphite equivalent to grey cast iron. The mechanical properties this influence not only formed by perlite, but also acting as stress concentrator....

The main goal of this paper is mathematical modelling and computer simulation isothermal decomposition austenite in steel. Mathematical nowadays becoming an indispensable tool for the prediction heat treatment results Besides that, can be applied understanding, optimization control microstructure composition mechanical properties Isothermal physically one most complex engineering processes. In ...

In this study, a new machining approach (aqueous machining) is applied for mill and its performance compared with traditional wet machining. AISI 1020 steel employed as the test material Taguchi statistical methodology implemented to analyze compare of two approaches. The cutting speed, feed rate, depth cut were parameters used both types machining, while selected response variables surface rou...
