Introduction The high current pulsed electron beam (HCPEB) technique has been proven to be an efficient method for surface modification of different metallic materials, which may improve the overall performance of modified material such as microhardness, corrosion resistance, and wear resistance [1-3].
In this case, nanostructure materials are unstable relative to the amorphous as they exhibit a higher free energy.
It is reasonably expected to utilize the surface nano-crystallization to improve the mechanical property of engineering materials by means of the HCPEB technique [10]. 3.
Summary This article describes the principle and characteristics of HCPEB treatment of materials.

The anisotropic character of local materials plays an important role in the crack initiation.
Because of plastic properties of materials, the combined stress would not exceed the yield stress, viz
Moreover, plastic materials are the low-carbon and low-alloy steels.

Additive manufacturing (AM) is gradually occupying a unique place as a viable industrial manufacturing technology for parts with complex geometry and difficult-to-machine materials.
Introduction Fused deposition modeling (FDM) is a popular extrusion-type additive manufacturing technology for thermoplastic materials.
One of the main attributes of FDM for its popularity is the freedom to use raw material filaments of a range of thermoplastic materials, including Acrilo-nitrile-butadiene Styrene (ABS) and polylactic acid, from any vendor.
The contouring zone consists of one or more contours of deposition of materials following the locus of the edge of the layer.

Introduction Al Alloy/SiC metal matrix composites (MMCs) are advanced materials which have wide applications in automobile, aerospace, sports and medical industries.
These materials are made to near net shape but to get into final shape they undergo machining.
Machining of Al alloy/SiC MMCs possess a great challenge as these are heterogeneous materials which contain hard SiC particles and soft Al matrix.

The following endodontic procedures benefit from the use of the microscope: • locating hidden canals that have been obstructed by calcifications and reduced in size; • removing materials such as solid obturation materials (silver points and carrier-based materials), posts or separated instruments; • removing canal obstructions; • assisting in access preparation to avoid unnecessary destruction of mineralized tissue, • repairing biological and iatrogenic perforations; • locating cracks and fractures that are neither visible to the naked eye nor palpable with an endodontic explorer; • facilitating all aspects of endodontic surgery, particularly in root-end resection and placement of retrofilling material.
Materials and Methods In the clinic of the Department of Endodontics, Faculty of Dentistry in Craiova, were examined a total of 31 extracted human second maxillary molars.
