Additive manufacturing is a good alternative to conventional methods for the production of near net shape geometries with high geometric complexity shorter lead times, being option dies die casting process. In this research, novel hot-work tool steel aluminum applications manufactured by laser powder bed fusion was investigated. As-built and stress-relieved (AS-B + SR) state established used as...

In the flat products steel industry, the hot rolling mill transforms the incoming slabs in a thin coil which then can be processed to obtain the final products. Thickness is reduced by pulling the plate between two parallel rolls while moving the upper work roll. The effect of uneven thickness at both sides can produce deviations in the longitudinal direction of the slab, which have to be manua...

SKD 11 tool steel is among the most popular metals in mold industries for making different kinds of cold work molds and dies with high accuracy and long service life. The demand for higher quality, lower manufacturing costs, particularly the environmentally friendly characteristics, have provided the stimuli for manufacturers and researchers to find alternative solutions. An excellent media is ...

Friction surfacing is an emerging surface engineering technology, developed on the basic principle of friction welding, for depositing wear and corrosion resistant metallic coatings. In the present work coating of tool steel M2 were made on mild steel by friction surfacing by using 2 factorial designs with 3 factors at two levels for each. Process parameters developed a satisfactory deposition ...

Hard turning is the latest technology and is used to turn hard materials by using cutting tools like CBN and PCBN. Certain hard materials like titanium, Inconel and stainless steel are pronounced as difficult to cut materials. The superior cutting tools effectively machine such hard materials and produces desirable surface roughness with less tool wear. The present research was carried on hard ...

The oxidation of stainless steels 304 and 304L during hot rolling is studied in this paper. Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity...

The wear mechanisms of cutting tools made of tungsten-carbide (WC), PCBN and PCD were investigated using the tool life and temperature results available in the literature. For tool/work combinations WC/steel and PCBN/hardened-steel, under practical conditions, tool wear was found to be greatly influenced by the temperature. It was concluded that the most likely dominant tool wear mechanism for ...
