The Effect of Heat Treatment on the Mechanical Properties of SAE 1035 Steel

Abstract

The effect of various heat treatment operations (annealing, normalizing, tempering) on mechanical properties of 0.35% carbon steel was investigated. The change in the value of endurance limit of the material as a result of the various heat-treatment operations were studied thoroughly. It was found that the specimens tempered at low temperature (200°C) exhibited the best fatigue strength. Microscope was used to characterize the structural properties resulting from different heat treatment processes. The results from the tensile tests impact tests and hardness tests showed that the mechanical properties variate at every heat-treatment conditions. The microstructure of differently heat-treated steels was also studied.

Effects of Repeated Heat Treatments on the Wear Resistance of Pre-Carburized Steel

“…The results of the wear tests were assessed using the Archad's or Rabinowicz's equations [30], which determine the wear rate and wear coefficient by relating the cumulative lost volume per sliding distance with the wear resistance through the following linear equation: 𝑽 = 𝒌. 𝑭. 𝑺 ∴ 𝒌 = 𝑽 𝑭. 𝑺 (1) where:…”

“…Friction fusion welding is a widely employed commercial technique, with its applications predominantly linked to the assessment of mechanical properties of various materials, such as 0.35 carbon steel, following diverse heat treatment processes including annealing, normalizing, and tempering [1]. The tensile strength, impact resistance, and hardness of these materials have been reported to vary substantially based on the heat treatment condition [1]. Investigations into the effects of conventional thermal treatments on the wear resistance of AISI H13 tool have been conducted.…”
