Effect of Nitrogen‐Substituted Carbon on Thermal Stability of Cr‐Mo‐V Hot‐Working Die Steel
Steel Research International, 2020To extend service life of Cr‐Mo‐V hot‐working die steel, a method of alloying with nitrogen‐substituted carbon is proposed. The mechanical properties of the test steels in the long‐time heating and holding process are measured.

Hot-worked microstructure and hot workability of cold-work tool steels
Materials Characterization, 2018Abstract The hot workability of two cold-work tool steels were evaluated and compared. A D2 and an advanced alloy based on 8% Cr steels (TDx) were deformed at high temperatures between 900 and 1100 °C with strain rates 0.001–10 s− 1 via hot compression test.

Working Hot: Materialising Practices
Women’s Philosophy Review, 2000This chapter is an early attempt to conceptualise art in new materialist terms as a more-than-representational practice. The chapter begins with the observation that the influence of literary theory and cultural studies on visual art theory has situated the visual arts firmly as a discursive and representational phenomenon, whereby visual ...

Abstract VDC is an air-hardening 5% chromium die steel recommended for a wide range of hot work applications requiring resistance to heat and abrasion, and is particularly useful for white metal die casting and extrusion applications. It is equivalent to AISI TYPE H13.

Abstract This chapter discusses the effects of hot working on the structure and properties of steel. It explains how working steels at high temperatures promotes diffusion, which helps close cavities and pores, and how it changes the shape and distribution of segregates, offsetting their effect.

Abstract BETHLEHEM HOT WORK 8 alloy is a hot-work tool steel having high wear resistance in the higher range of operating temperatures. It also has high resistance to surface wash and heat-checking. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness.

Before introducing the results of hot-working experiments, the techniques and their limitations are described. Microstructural observations and mechanical measurements are discussed separately. The microstructure of hot-worked single-phase alloys consists of polygonized cells; the degree of polygonization increases with rise in temperature, decrease in

Serum Enzyme Changes in Hot Work
Journal of Occupational and Environmental Medicine, 1977A total of 31 workers employed in hot work in small-scale foundries, 13 gardeners engaged at light jobs under the sun and 16 sedentary persons were selected after medical screening for a study of the levels of serum enzymes [glutamic oxalacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), lactic dehydrogenase (LDH) and adolase].
