Tensile Properties of Ferrite-austenitic Welded Joint
Very often, in order to optimized welded constructions, some of their parts are made of heterogeneous steels. For example, microalloyed steels are in use for cars chassis making and high alloyed steels for different constructions making. From that reason, it’s not rare to find welded joints between ferrite microalloyed and austenitic highalloyed steels. As a rule, these joints are welded by usi...

متن کاملThermo-mechanical Cracking of a New and Laser Repair Welded Die
The paper presents the analysis of thermo-mechanical fatigue cracking of die casting die during industrial use. An innovative, production friendly approach to monitor the surface crack dimensions was introduced, which is based on measuring defect-fi n on the casting part. A new four moulds die casting die was monitored 40 000 cycles in order to complete the production series. The production was...
متن کاملAnalysis of Cracks in the Pulsed Nd:YAG Laser Welded Joint of Nickel-Based Superalloy
The weldability of GTD-111 nickel-based superalloy by pulsed Nd:YAG laser welding with an average power of 250 W was studied, and the microstructural evolution and cracking characteristics were also investigated. The solidification cracking of the fusion zone (FZ) and the intergranular liquation cracking in the heat affected zone (HAZ) were observed in the joint. Solidification cracking was cau...
متن کاملJoint cracking and popping: understanding noises that accompany articular release.
Articular release is a physiologic event that may or may not be audible. It is seen in patients with healthy joints as well as those with somatic dysfunction. After an articular release, there is a difference in joint spacing-with the release increasing the distance between articular surfaces. Not all noise that emanates from a joint signifies an articular release. A hypothesis about the noise ...
