1. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål
M1-uppsats, Högskolan i Gävle/MaskinteknikSammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER
2. Melt pool Geometry and Microstructure Characterization in Additively Manufactured WE43 Alloy
Master-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Mg-RE based alloys have exhibited promising properties in application for biodegradable implants. This work provides a systematic study on the characterization of melt pool geometry and profile for one such alloy, WE43. LÄS MER
3. Sample quality effects of laser cutting : An empirical study on the heat affected zone and the surface quality in laser cut samples
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : This study has been conducted with the aim to examine the extent of the heat affected zone in order to use laser cutting when making samples for tensile testing. When cutting with a laser the material absorbs heat energy from the laser beams which causes changes in the microstructure. LÄS MER
4. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). LÄS MER
5. Assessment of static performance of LKAB´s welded mesh : Laboratory testing and analysis
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Surface support is an areal support, which is installed on rock excavation surface to prevent bulking of rock mass and retain loose rock fragments. Welded wire mesh is one type of surface support. Literature study indicates that there is a wide range of testing methods on mesh. LÄS MER
