TLDR
In this paper, the influence of process parameters such as cutting speed, feed and depth of cut on surface roughness on both materials was compared and the results showed that the multiphase microalloyed steel exhibited high surface finish than air-cooled steel.Abstract:
Multiphase ferrite–bainite–martensite microalloyed steel produced through a two-step cooling followed by annealing route and a ferrite–pearlite steel obtained through air-cooling after forging were subjected to turning operation. The influence of process parameters such as cutting speed, feed and depth of cut on surface roughness on both materials was compared. The results show that the multiphase microalloyed steel exhibited high surface finish than air-cooled steel. The analysis of variance shows that the contribution of cutting speed and depth of cut on surface roughness are insignificant for both ferrite–bainite–martensite and ferrite–pearlite microstructures.read more

Effect of cutting parameters on cutting force and surface roughness during machining microalloyed steel: Comparison between ferrite–pearlite, tempered martensite and ferrite–bainite–martensite microstructures
TL;DR: In this paper, three different microstructures, namely ferrite-pearlite, tempered martensite and ferrite bainite-martensite of 38MnSiVS5 microalloyed steel, were produced using controlled thermomechanical process.

Machinability of multiphase microalloyed steel
TL;DR: In this article, the machining of multiphase (ferrite-bainite-martensite) microalloyed steel was carried out in a high speed lathe to assess the machinability.
