21. The influence of tool steel microstructure on galling
Sammanfattning : In sheet metal forming (SMF) of materials such as stainless steels there is a major problem with transfer and accumulation of sheet material to the metal forming tool surface. The problem is known as galling; a sort of severe adhesive wear, which results in severe scratching of produced parts. LÄS MER
22. Chromium martensitic hot-work tool steels : damage, performance and microstructure
Sammanfattning : Chromium martensitic hot-work tool steel (AISI H13) is commonly used as die material in hot forming techniques such as die casting, hot rolling, extrusion and hot forging. They are developed to endure the severe conditions by high mechanical properties attained by a complex microstructure. LÄS MER
23. Healthcare context for knowledge translation in Vietnam : Development and application of the Context Assessment for Community Health (COACH) tool
Sammanfattning : The failure to translate evidence into clinical practice has been repeatedly highlighted. This failure is partly attributed to disregarding the context within which healthcare is delivered. LÄS MER
24. Textured insert for improved heat extraction in combination with high-pressure cooling in turning of superalloys
Sammanfattning : Heat generated in a machining process is a common and critical obstacle faced in today's machining industries. The heat generated in the cutting zone has a direct negative influence on the tool life which, in turn contributes to increase the manufacturing costs. LÄS MER
25. Investigation on the Influence of Nodularity in Machining of Compacted Graphite Iron (CGI)
Sammanfattning : Stringency of environmental legislation on emission rates and increasing vehicle performance requirements are pushing the automotive and heavy truck industries to find new solutions for their diesel engines. Two potential opportunities to address these challenges involve increased combustion pressure to obtain more efficient combustion or reducing the weight of the engine. LÄS MER
