In the current study, effect of varying Silicon Carbide particulate on the mechanical properties of Aluminium based alloy automobile brake disc component was investigated. The result of experimental investigation on mechanical properties of Silicon Carbide particle reinforced Aluminium Matrix was achieved for composite brake disc using universal tensile test machine, Rockwell hardness testing m...

The effects of applied load, sliding speed and sliding distance on the dry sliding wear behavior of aged Al-SiCp-Gr composites were investigated. The specimen were fabricated by stir-casting technique. The pin-on-disc wear testing machine was used to investigate the wear rate by design of experiments based on L27 using Taguchi technique. Sliding distance was the most important variable that inf...

Accurate determination of the position of final solidification point or crater end at ArcelorMittal Dofasco’s No. 2 Continuous Caster (CC) is essential for maximizing both casting speed and equipment utilization. The caster is equipped with one 900-mm long, straight, water-cooled copper mold, and produces 218-mm thick slabs with a maximum width of ~1,600 mm. The casting speed range at the caste...

introduction: prefabricated metal and ceramic posts can be used with different kinds of core materials as an alternative to the conventional casting post and cores. it is unclear how these post and core systems can withstand different kind of forces in the mouth. the purpose of this study was to compare the fracture strength of endodontically treated, crowned maxillary incisors restored with ca...

Titanium is an ideal material for use in prosthodontics because of its biocompatibility, corrosion resistance, and mechanical strength combined with its lightweight. Recently the use of titanium and titanium alloys for fixed restorations has increased substantially, mainly due to the improvement of techniques for the casting titanium and its alloys. This article reviewed the studies on titanium...

We present UML-CASTING, a prototype tool for computer-assisted generation of test suites from UML models. The concept underlying Casting is that a large part of test cases corresponding to a given test strategy can be obtained automatically from the text of the specification. A test strategy consists of a set of decomposition rules that are applied to the expressions in a specification in order...

Background and Aim: Different methods and materials are available for post and core (P&C) fabrication. We aimed to compare the fracture resistance and failure modes of endodontically treated maxillary central incisors restored with six different P&C systems. Materials and Methods: In this in-vitro study, after endodontic treatment and coronal preparation of 60 maxillary central incisors, six d...

Foundry is one of the activities that has contributed to evolve the society, however, the manufacturing process is carried out in the same manner as it was many years ago. Therefore, several defects may appear in castings when the production process is already finished. One of the most difficult defect to detect is the microshrinkage: tiny porosities that appear inside the casting. Another impo...
