The use of mineral-based cutting fluids in machining has the drawback affecting environment and industries are under pressures to reduce its favor cleaner productions. In this regard, vegetal-based can be a superior alternative, provided they improve technical outcomes. milling process, dry is commonly performed, however, application using minimum quantity lubricant (MQL) method proven advantag...

This paper studies the influence of different substrate materials on phase composition, microstructure, microhardness, and wear resistance Ni-Cr-B-Si-C-Ti-Al plasma spray coatings. Two types metals were studied – AISI 1045 steel Pig-P3 Si grey cast iron. It has been found that in as-coated condition surface layers have a composition γ-Ni, Cr23C6, γ-TiAl, TiN, α-Ti(N, O) substrate, α-Ti, Ni3B, C...

The objective of this paper is to describe and analyze a series of nonlinear finite element analyses used to compare three design methods for locally slender, braced, steel beams and columns. The three design methods are: (i) the hot-rolled steel AISC Specification, (ii) the coldformed steel AISI Specification which uses the effective width method throughout, and (iii) the cold-formed steel Dir...

In this research work, investigations are carried out on Continuous Wave (CW) Nd:YAG laser welding system after preliminary experimentation to understand the influencing parameters associated with laser welding of AISI 304. The experimental procedure involves a series of laser welding trials on AISI 304 stainless steel sheets with various combinations of process parameters like beam power, beam...

Medium Carbon Steel AISI 1045 has a wide variety of applications in vehicle component parts & machine building industry. Surface roughness and Material Removal Rate are the main quality functions in high speed turning of medium carbon steel in dry conditions. In this study, the optimization of two response parameters (Surface roughness and Material Removal Rate) by three machining parameters (c...

A high quality joint between tool steel and stainless steel alloys is hard to achieve with the conventional welding process. In this study, a new process of joining semi-solid AISI D2 tool steel and AISI 304 stainless steel using a partial remelting method is proposed. Metallographic analysis and Vickers hardness tests were performed. The results obtained from investigating the basic geometries...

In the present work CO2 continuous laser welding process was successfully applied and optimized for joining a dissimilar AISI 316 stainless steel and AISI 1009 low carbon steel plates. Laser power, welding speed, and defocusing distance combinations were carefully selected with the objective of producing welded joint with complete penetration, minimum fusion zone size and acceptable welding pro...
