Best practice in heat treatment of large dies made of hot work tool steels
Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production. These elements include extruding dies, pressure casting dies, moulds, punches and various other elements for plastic shaping of other materials preheated to temperatures in the range of 250-700 °C (Fig. 1). Since shape stability constitutes...
متن کاملMaterials on Dies for Pressure Die Casting
In the contribution the stress of die materials of thermal fatigue is defi ned and material life is derived theoretically and compared with the measured values. The important properties of the die materials as thermal conductivity, coeffi cient of thermal expansivity, modulus of elasticity and mechanical properties are described. Binding to it single die materials as carbon steels and chrome-tu...
متن کاملThe spirit never dies
Received: 3 October 2005 Accepted: 3 October 2005 I met Claudio as late as the year 2000. We had known one another by name for some time and we had had the occasional exchange of e-mails and a few telephone calls but did not happen to meet in person, as we operated in slightly different fields. I deeply regret that. Claudio will surely remain an important intellectual figure in the interdiscipl...
متن کاملWho dies from hernia?
Over 700 deaths in England and Wales each year are ascribed to an underlying cause of abdominal hernia, considerably more than for cholelithiasis, pancreatitis or inflammatory bowel disease. Abdominal hernias are considered amenable to surgical intervention, therefore hernia mortality is regarded as largely avoidable. None the less substantial variations in mortality exist at district level wit...
متن کاملDying among older adults in Switzerland: who dies in hospital, who dies in a nursing home?
BACKGROUND Institutional deaths (hospitals and nursing homes) are an important issue because they are often at odds with patient preference and associated with high healthcare costs. The aim of this study was to examine deaths in institutions and the role of individual, regional, and healthcare supply characteristics in explaining variation across Swiss Hospital Service Areas (HSAs). METHODS ...
