Book Description
LES OUTILS DE COUPE CERAMIQUES PERMETTENT, PAR L'AUGMENTATION DES VITESSES DE COUPE, L'AMELIORATION DES RENDEMENTS D'USINAGE. CE TRAVAIL A CONSISTE A DEVELOPPER UN COMPOSITE A MATRICE ALUMINE 80- OXYNITRURE D'ALUMINIUM 20 VOL. POURCENTS RENFORCE PAR DU CARBURE DE SILICIUM SOUS DEUX MORPHOLOGIES: POUDRE ET PLAQUETTE. LES ETUDES ONT PORTE SUR LES AMELIORATIONS DU PROCEDE DE FABRICATION ET L'EVALUATION DU COMPORTEMENT EN FROTTEMENT ET EN COUPE D'UN ACIER DUR (Z38CDV5) ET UN SUPERALLIAGE BASE NICKEL (INCONEL 718). OUTRE L'INTERET DE LA FORMATION IN SITU DE L'OXYNITRURE D'ALUMINIUM (REACTION ALUMINE-NITRURE D'ALUMINIUM) AU COURS DU FRITTAGE SUR LA DENSIFICATION FINALE, IL EST MONTRE QU'UNE HOMOGENEISATION PAR ATTRITION CONDUIT A UN CERTAIN RENFORCEMENT DE LA MATRICE. LES PROPRIETES MECANIQUES DU MATERIAU A POUDRE OPTIMISE SONT MAINTENUES JUSQU'A 1000C. CONCERNANT LE COMPOSITE A PLAQUETTE, ON OBSERVE UNE REACTIVITE IDENTIQUE A CELLE DU COMPOSITE A POUDRE, MAIS A UNE TEMPERATURE PLUS BASSE. ON OBTIENT LES VALEURS MAXIMALES DE TENACITE (7 MLA. M) POUR UN DIAMETRE DE MOYEN DE 8 MICRONS ET UNE TENEUR EN PLAQUETTES DE 20 VOL. POURCENTS. DANS LES CONDITIONS DE FROTTEMENT TESTEES (FAIBLE PRESSION), L'USURE DES COMPOSITES FACE A L'ACIER EST NEGLIGEABLE, FACE A L'INCONEL L'USURE N'EST PLUS NEGLIGEABLE ET DEPEND DE LA GRANULARITE DE SIC ET DU TAUX D'OXYNITRURE. LES ESSAIS DE COUPE, REALISES A L'ECOLE CENTRALE DE NANTES, LABORATOIRE MATERIAUX, MONTRENT L'INTERET DES COMPOSITES RENFORCES PAR LA POUDRE POUR LE TOURNAGE D'ACIER DE HAUTE DURETE

Ceramic Materials
Author: Philippe Boch
Publisher: John Wiley & Sons
ISBN: 0470394544
Category : Technology & Engineering
Languages : en
Pages : 593
Book Description
This book is primarily an introduction to the vast family of ceramic materials. The first part is devoted to the basics of ceramics and processes: raw materials, powders synthesis, shaping and sintering. It discusses traditional ceramics as well as “technical” ceramics – both oxide and non-oxide – which have multiple developments. The second part focuses on properties and applications, and discusses both structural and functional ceramics, including bioceramics. The fields of abrasion, cutting and tribology illustrate the importance of mechanical properties. It also deals with the questions/answers of a ceramicist regarding electronuclear technology. As chemistry is an essential discipline for ceramicists, the book shows, in particular, what soft chemistry can contribute as a result of sol-gel methods.

High-temperature Structural Materials
Author: Robert Cahn
Publisher: Springer Science & Business Media
ISBN: 9401105898
Category : Technology & Engineering
Languages : en
Pages : 333
Book Description
Conventional materials, such as nickel based alloys, will not be able to match the required performance specifications for the future generation of high temperature materials. This book reviews the characteristics and potential of a wide range of candidate superalloy replacements, such as ceramics, intermetallics, and their composites. Particular attention is devoted to the problems of processing and design with these materials.

Hybrid Fiber Composites
Author: Anish Khan
Publisher: John Wiley & Sons
ISBN: 3527346724
Category : Technology & Engineering
Languages : en
Pages : 420
Book Description
Fiber-reinforced composites are exceptionally versatile materials whose properties can be tuned to exhibit a variety of favorable properties such as high tensile strength and resistance against wear or chemical and thermal influences. Consequently, these materials are widely used in various industrial fields such as the aircraft, marine, and automobile industry. After an overview of the general structures and properties of hybrid fiber composites, the book focuses on the manufacturing and processing of these materials and their mechanical performance, including the elucidation of failure mechanisms. A comprehensive chapter on the modeling of hybrid fiber composites from micromechanical properties to macro-scale material behavior is followed by a review of applications of these materials in structural engineering, packaging, and the automotive and aerospace industries.
