Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

open access: yessteel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Thermovision analysis of a CNC milling machine

open access: yesDesign of Machines and Structures, 2019
This article concerns a thermovision analysis of a DMU40 5-axis CNC milling machine [1] using a thermal camera. First I specify the measuring instrument and I present the layout of the measurement. Before this measurement I created a thermal model of machine tool and I analysed it by finite element method. After evaluating simulation results I make the

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.
