The deep cryogenic treatment is a complementary operation that is done on a variety of tool steels aimed at improving their abrasion resistance and hardness. In the case of the H13 hot-work steel, which is widely used at high temperatures as a hot-deformation tool, we need to determine the efficiency of subzero treatment on it at the working temperature. In this regard, this paper is focu...

surface roughness of engineering parts is very significant property that effectively influences on the wear and fatigue strength. there are many methods for improving surface quality of engineering parts such as grinding, lapping and honing. one of the methods for improving surface quality is roller burnishing. roller burnishing improves surface quality of engineering parts by means of cold wor...

Cold forging is often applied in the fastener industry. Wires in coil form are used as semi-finished products for the production of billets. This process usually requires preliminarily drawing wire coil in order to reduce the diameter of products. The wire usually has to be annealed to improve its cold formability. The quality of spheroidizing annealed wire affects the forming quality of screws...

The floor beams of steel buildings, cold-formed steel floor joists in particular, often require large web openings, which may affect their shear capacities. A cost effective way to mitigate the detrimental effects of such openings is to weld/fasten reinforcements. A difficulty associated with an experimental investigation to establish suitable reinforcement schemes for openings in shear zone is...

Mono- and multilayer coatings can be suitable alternatives to traditional bulk materials due their favorable mechanical properties. Thanks the ever-evolving coating technology process, there are a wide variety of types today, such as soft, hard, or super-hard that made with single coatings.
 Adhesion damage is especially important for coated tools, where reduce tool life result in deterior...

Abstract Cold spray can produce deposits from a broad range of materials but reports on cold steels are still limited to the few steel families demonstrating high ductility and medium strength. Softening agglomeration powders via heat treatment in rotary tube furnace were investigated as promising ways improve H13 tool powder sprayability. By adjusting starting size, well conditions (maximum te...

The objective of this paper is to explore the potential strength and serviceability implications of metallic foams, specifically steel foam, utilized as a thin-walled channel structural member. A typical advantage sought in the selection of a thin-walled member is minimal weight. However, the stability of the thin walls and the related limit states constrains the extent to which weight minimiza...

Bu çalışmada tel erozyon (WEDM) yöntemi kullanılarak Sverker 21 soğuk iş takım çeliğinin kesme parametrelerinin işleme sonrası malzemede oluşan beyaz tabaka ve yüzeyi sertliğine etkileri incelenmiştir. Yüksek alaşımlı çeliğin kullanılmasındaki amaç; içerdiği alaşım elementi karbon oranına bağlı olarak yüksek sertlik, aşınma dayanımı tokluk özelliklerinden dolayı kalıpçılık endüstrisinde yaygın ...
