The Progress of Bainitic Transformation during Austempering in Connection with the Alloying of Unconventional AHS Steels

It is well known that incomplete bainitic transformation during austempering treatment is mainly caused by the supersaturation of austenite with carbon. Such supersaturated austenite becomes more stable and further stabilization is led by silicon alloying. Stable austenite does not transform and&...

Heat treatment of bimetals produced by selective laser melting of MS1 maraging steel on conventionally produced 42SiCr martensitic steel

One approach to producing hybrid bimetallic parts is to additively manufacture a new material onto a conventionally manufactured base material. This technique can expand the potential applications of additive manufacturing and offer new solutions for the engineering design of hybrid parts. I...

Stabilizing legs with possibility of loss of stability to protect glass fibre reinforced polymer tank

This work focuses on the optimization of the stabilizing legs of a Glass Fibre Reinforced Polymer under- ground tank. More specifically, the aim was to find a structure of the legs that compensates for the pos- sible failure of the tank when it is filled after being&...

Effect of Cylinder Roughness on Strouhal Number

The main goal of this paper is to establish a better understanding of the relationship between a Strouhal number and surface roughness. Hot-wire anemometry was used to evaluations the characteristics of turbulent flow behind circular cylinders with different relative roughness 0% (smooth...

Microstructure and Mechanical Properties of 3D Printed Tool Steel after Various Precipitation Hardening Treatments

Precipitation hardening is one of the most frequently used methods of the post-processing heat treatments of 3D printed tool steel 1.2709, as it increases the yield and ultimate tensile strengths of the steel. Within this work, the broad temperature range of 250°C – 550°C was&...
