A study on the effect of hot isostatic pressing (HIP) on the microstructure and tensile properties of A356-T6 cast aluminum alloy cast into a plate and machined to a test bar according to ASTM E8M found the solution treatment was 1,000F (538C) for 5 hours; artificial aging was 320F (160C) for 4 hours.
Meanwhile, Bodycote's hot isostatic pressing unit saw sales rise seven per cent to pounds 43.
Exceptions to this rule are targets made by the hot isostatic pressing process for powdered materials.
Internal porosity can be eliminated by Hot Isostatic Pressing (HIP), using Argon gas at 14,000 psi and a temperature of over 2372F (1300C) to densify and eliminate porosity in carbide materials.
The emphasis then shifted to hot isostatic pressing (HIP), either to achieve additional densification of a sintered part or to directly densify a powder compact encapsulated in a glass envelope.
Additional value-added products and services include hot isostatic pressing, specialty coatings, research and development, supply chain management, specialty tools, molds, and machinery.
These areas were weld repaired and cleaned, and the casting was sent to hot isostatic pressing (HIP) to help ensure metal quality and meet the nondestructive testing (NDT) requirements.
Hot isostatic pressing saw a year-onyear sales growth of around 16 per cent, while Bodycote's health science and environmental unit experienced some margin pressure due to seasonal issues.
