The heat treatment cycle is designed to obtain a hardness of 25-30.HRC in EN 24 Material where as the regular hardening and tempering of EN24 material results in to higher hardness values. The heat treatment cycle involves oil quenching while harden ing and forced air quenching for tempering....
The main intension is to optimize the cutting parameter.Generally hard turningis turning process in which work material whose hardness about 46-69 HRC are used. Thus, various sort of tipped tools are used for turning operation. The orthogonal array, signal to noise ratio are employed to study ...
An experimental investigation of laser surface hardening of EN24 alloy steel using Nd-YAG laser in atmospheric medium was conducted to understand the influence of laser parameters like laser power, travel speed on the microstructure and material hardness. The laser heat input is allowed to harden ...
