The AlSi10Mg alloy was developed using a selective laser melting (SLM) process, followed by stress relieving at $$300^\circ \hbox {C}$$ for 2 and 4 h respectively. The effect of the heat treatment time on the microstructural and mechanical properties

SYNOPSIS The mechanical properties and microstructure of AlSilOMg alloy samples that were printed by selective laser melting (SLM) were studied to determine the effect of processing parameters and building orientation. After printing, the alloy was s

During the heat treatment of springs for railway bogies, phase transformations and oxidation occur and it is important to know transformation temperatures and oxidation rates to optimise the process. Oxidation and decarburisation can adversely affect

Excessive wear rates on railway wheels can result in rolling-stock derailments. If wear is detected early the possible derailments can be prevented by prematurely replacing wheelsets, although the inventory cost and maintenance downtime remain a chal

In this study we examined the behaviour of the 52CrMoV4 spring steel at various tempering temperatures and soaking times. The hardening and quenching process was set up to achieve a minimum hardness of 800 HV by selecting an appropriate quenching med
