Heat Affected Zone. That portion of the base metal that has not been melted but whose microstructure or mechanical properties have been altered by the heat of welding, brazing, soldering, forming, or cutting.
Health Action Zones (HAZ) are partnerships between the NHS, local authorities, the voluntary and private sectors and local communities which represent a new approach to public health, linking health, regeneration, employment, education, housing and anti-poverty initiatives to respond to the needs of vulnerable groups and deprived communities.
Health Action Zones. strategies aiming to improve health services by forming new partnerships and reducing poor health
Health Action Zone - an iniative which brings together local organisations and community groups to focus efforts and resources to tackle the causes of ill health and reduce health inequalities.
Health Action Zone. a national initiative to target health improvement with fast-track initiatives which sets health in its widest context – looking at the whole community and its contribution to good health as well as providing better integration of services for the prevention of ill health and the provision of treatment and care.
Health Action Zone. A new initiative to bring together organisations within and beyond the NHS to develop and implement a locally agreed strategy for improving the health of local people.
Health Action Zones. HAZ's are partnerships between the NHS, local authorities, the voluntary and private sectors, and local communities. As well as tackling major health problems, they link work on health, regeneration, employment, education, housing and anti-poverty initiatives in innovative ways.
HEAT AFFECTED ZONE. Part of parent metal which is metallurgically affected by welding but not melted. (Weld zone, fusion zone.)
Heat Affected Zone. During laser cutting of steels a huge amount of energy is conducted into the work piece resulting in changes in the material properties and the microstructure of the steel. This activity results in a narrow zone exactly adjacent to the laser cut that experiences changes in material properties. Typically, the changes occur either as grain refinement, or as precipitation of carbides (which are harmful for corrosion resistance properties of steel) and other impurities such as sulfides and phosphides. The entire region which differs from the base material in properties can be defined as the heat affected zone or HAZ.
