Mechanical Properties of the Brazed Diamond Wire.
In order to evaluate the changes of mechanical properties after brazing, the tensile strength, extensibility, torsional strength and bending strength of the brazed diamond wires were measured on a universal material testing machine, with the same tensile speed of 1 mm/min.
In order to appraise the bending properties of the brazed wires, the wires used in experiments were bended in different directions to a certain degree of arc and then were observed under the micro-scope.
Therefore, in order to obtain a slice with low damage, little scratches and high-precision surface shape, the diameter size variation of the brazed diamond wire is an important factor affecting the cutting quality and must be controlled in a very small range of variation.

It can produce the high strength, good performance of complex precision mechanical parts.

It can improve the hydrophilic property of polyester fabric while still maintaining the original properties of the fiber.
A Three-factor three-level orthogonal test was designed based on processing power (Po), processing time (T), pressure (Pr) of three levels in order to study how these factors affect the hydrophilicity of poyester fabric.
Through orthogonal test and range analysis, various factors of plasma treatment process and several factors of chitosan finishing are studied and the variation tendency depending on the factors are shown.

The acoustic signals were strongly related to the behavior of the arc column, the molten pool and droplet transfer in gas metal arc welding(GMAW).In this study, all the work pieces (JIS SS400) were welded at the same speed with different currents using a gas metal arc; the purpose was to observe the relationship between these factors.
The properties of the audio signals were analyzed by the wavelet-based channel energy.
Welding power and the interactive time during welding are the two influential factors affecting weld quality.
In this paper, all the work pieces (SS400) were welded at the same speed using different currents during the gas metal arc welding process in order to observe the relation between these factors.

Abstract:-The high-performance solid propellants play very important role in defense industry, which required highly energetic binders with good mechanical properties.
Introduction: Polyurethane elastomers are widely used engineering materials and are well known for their outstanding mechanical, thermal and adhesive properties, having broad range of applications like water permeability, low temperature resistance and in composite propellant manufacturing technology.
In addition to its application, kinetics of its polymerization, structure of its ingredients i.e. isocyanates or alcohols, are an important factors to affect the polyurethane formation [1-3].
Although GAP is unique energetic binder with positive heat of formation (+117.2 kJ.mol-1), high density, but shows inferior mechanical behavior due to poor flexibility of backbone, While HTPB exhibits high flexibility, low glass transition temperature with superior mechanical properties [10].The target goal is to develop the Interpenetrating polymer network (IPN) of GAP and HTPB with improved Mechanical properties for the composite solid rocket propellant, a comprehensive study regarding reaction conditions like temperature and concentration of the catalyst for curing is required.
Activation energy for the reaction between GAP-IPDI and HTPB-IPDI can be determined by using the Arrhenius equation which is as given below: K= Ae - Ea/RT (1) Where, k is the rate constant; Ea is the activation energy; T is the absolute temperature in Kelvin; A is known as pre-exponential factor and R is gas constant.

Additionally, other properties such as creep-fatigue, high temperature rupture resistance, ductility and fracture toughness are affected leading to embrittlement in the alloy [10, 12].
