1. Toughness of Tool Steel
Abstract : Toughness is the ability to resist tensile stresses in the presence of a notch or crack. Sometimes gross cracking of industrial tools, mould or dies, occurs due to insufficient toughness. As the economic consequences of the gross cracking are serious, the toughness of industrial tool material, generally tool steel, is of paramount importance. READ MORE

2. Mechanical Recycling of Engineering Thermoplastics using Alloying Techniques
Abstract : The aim of this thesis is to indicate routes by which recycled engineering thermoplastics (ETP) can be upgraded using alloying techniques. Recycled ETP have often been subjected to long-term service-induced degradation, so that the residual properties of recycled ETP need to be improved. READ MORE

3. The fracture mechanisms in duplex stainless steels at sub-zero temperatures
Abstract : The aim of the thesis was to study the susceptibility for brittle failures and the fracture process of duplex stainless steels at sub-zero temperatures (°C). In the first part of the thesis plates of hot-rolled duplex stainless steel with various thicknesses were used to study the influence of delamination (also known as splits) on the fracture toughness.

4. Fracture toughness properties of duplex stainless steels
Abstract : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. READ MORE

5. Effect of Microstructure on Mechanical Properties of High Strength Steel Weld Metalsn
Abstract : The effects of variations in alloying content on the microstructure and mechanical properties of high strength steel weld metals have been studied. Based on neural network modelling, weld metals were produced using shielded metal arc welding with nickel at 7 or 9 wt. %, manganese at 2 or 0.5 wt. READ MORE
