Book Description
Even since its discovery in 1948, the use of ductile iron is increasing continuously, this is due to the combination of its various excellent mechanical properties. Excessive amount of research is being carried out to develop even better properties. Austempererd ductile iron is the most recent development in the area of ductile iron or S.G. iron. This is formed by an isothermal heat treatment of the ductile iron. The newly developed austempered ductile iron is now replacing steel in many fields so it has becoming very important to various aspects of this material. In the present work the effect of copper along with the process variables (austempering temperature and austempering time) on the properties (Hardness, Tensile strength and Elongation) and microstructure of ductile iron is studied. With increasing austempering time hardness, tensile strength and elongation are increasing but with increasing austempering temperature hardness and tensile strength are decreasing and elongation increasing. Austempered ductile iron with copper is showing some higher strength, hardness and lower elongation than the austempered ductile iron without copper. In microstructure ferrite is increasing

Book Description
This study describes the resistance to penetration and the damage to austempered ductile iron (ADI) from ballistic impacL The resistance to penetration is determined with an average velocity with a 50% probability for complete penetration, the V-50 ballistic limit. The responses of the ADI material to impact are shown by observations of penetration modes, microstructural changes, and fracture topographies. Mechanical properties and ballistic limits are shown for two variations of the austemper process. ADI targets reveal a capability for multiple impacts without structural failures. Penetration modes include ductile hole growth, radial fracture, petaling, and scabbing. V-50 velocities of ADI with lower values of hardness and strength are equal or greater than the V-50 velocities of ADI with higher values of hardness and strength. Graphite spheroids of this ductile cast iron appear to affect plastic deformation and penetration modes by localizing stresses, microstructural changes, and fracture.

Book Description
Recent advances in metallurgy of hypereutectoid steels and cast irons show that unique properties, such as ultrahigh hardness and strength, and superplasticity, are achievable. This book focuses on the mechanical properties of hypereutectoid steels and cast irons as influenced by thermomechanical processing and microstructure.

Book Description
"The quality of Austempered Ductile Iron ADI, made from Indonesian-produced Ferro-Casting Ductile Iron, FCDI as base materual is discussed. FCDI that is made for routine consumption in Indonesia; not especially as ADI base material is assessed for chemical composition and mechanical properties. It is then austempered at austenisation temperature 950 degrees C with 1 hour holding. Three astempering temperatures 300, 350 and 400 degrees C, were investigated with 1 hour holding time using fluidized bed furnace. Metallographic examinations, tension tests and Brinell hardness number tests, were then carried out for the resulting ADI. Based on ASTM A897M-90 the products of austempering temperature 300 and 350 degrees C can be classified as ADI 850/550/10. This shows that the Indonesian-produced FCDI base material can be used for ADI production." -- abstract.

Book Description
Cast Iron Technology presents a critical review of the nature of cast irons. It discusses the types of cast iron and the general purpose of cast irons. It also presents the history of the iron founding industry. Some of the topics covered in the book are the description of liquid metal state; preparation of liquid metal; process of melting; description of cupola melting and electric melting methods; control of composition of liquid metal during preparation; description of primary cast iron solidification structures; and thermal analysis of metals to determine its quality. Solidification science and the fundamentals of heat treatment are also discussed. An in-depth analysis of the hot quenching techniques is provided. The graphitization potential of liquid iron is well presented. A chapter is devoted to microstructural features of cast iron. The book can provide useful information to iron smiths, welders, students, and researchers.
