The effect of soaking time on mechanical properties of roll-bonded AA3003 and AA4045 used for heat exchangers

Moema, Joseph; Siyasiya, Charles Witness; Morudu, Veronica K.; Buthelezi, Thokozani (MDPI, 2023-09)

Due to the rising need for energy saving, high-performing automotive heat exchangers, demand has significantly grown in recent years. As a result, effective fin-tube heat exchangers are becoming more popular. These tubes ...
Effects of lubrication on wear and rolling contact fatigue behavior of class B wheel steels against R350HT rail steels using a twin-disc wear simulator

Leso, Tshenolo Phinah; Siyasiya, Charles Witness; Mostert, R.J. (Roelf); Moema, Joseph (Taylor and Francis, 2023)

Wear and rolling contact fatigue (RCF) are major causes of delays and unavailability of rail systems. The presence of lubricants at the rail and wheel interface influences wear and RCF. Lubricants include naturally occurring ...
Effects of slip ratio on wear performance of class B wheel steels against softer R260 rail steels using the twin disc setup

Leso, Tshenolo Phinah; Siyasiya, Charles Witness; Mostert, Roelf Johannes; Moema, J. (Southern African Institute for Industrial Engineering, 2022-11-11)

A train experiences different slip ratios at the wheel/rail contact point as it moves along the rail track, which influences the rolling contact fatigue (RCF) and wear properties of wheel and rail materials. This variation ...
Tracking the railway line in-service behaviour through metallurgical and mechanical property characterisation

Mwamba, A.; Mabeba, A.D.; Moema, Joseph; Phasha, M. (AOSIS Open Journals, 2021-12)

Wear, contact-impact, fatigue and corrosion properties are important factors initiating rail track degradation and are composition dependent. This work focuses on the effect of chromium content on the metallurgical and ...
