  • Pyrolytic Carbon for Biomedical Applications
    Article - 13 Jun 2002
    Pyrolytic carbon is biocompatible and thromboresistant. This combined with wear resistance, durability and strength make it an ideal material for artificial heart valves. The development of the...
  • Copper / Zinc / Aluminium Shape Memory Alloys
    Article - 22 Apr 2002
    CuZnAl SMA's are probably the least well known of the three main families of commercial SMA's. They use relatively cheap materials and can have transformation temperatures between + and -100°C. They...
  • Titanium - Applications
    Article - 4 Mar 2002
    The excellent properties possessed by titanium make it a highly useful material. Applications in aerospace (e.g. engines and structures)and industrial applications are covered, as are emerging...
  • Special Applications with Tungsten
    Article - 15 Feb 2002
    Cobalt-chromium-tungsten alloys often referred to as stellite, are a group of wear-resistant alloys with applications where a tough wear-resistant material is necessary.
  • Stainless Steel Grade Compositions for Ferritic, Duplex, Martensitic and Precipitation Hardening Stainless
    Article - 2 Jan 2002
    This article briefly outlines the chemical compositions and main applications for ferritic, duplex, martensitic and precipitation hardening grades of stainless steels.
  • Stainless Steel - Grade 630
    Article - 7 Nov 2001
    This grade combines high hardness and strength after suitable heat treatment. Corrosion and heat resistance are similar to grade 304. It is suited to production of long shafts which require no...
  • Stainless Steel - Grade 440 (UNS S44000)
    Article - 7 Nov 2001
    Suitable heat treatment can see this grade attain the highest hardness, strength and wear resistance of any stainless steel. This is due to the high carbon content. The composition is optimised for...
  • Stainless Steel - Grade 420 (UNS S42000)
    Article - 23 Oct 2001
    420 is a higher carbon version of grade 410. When fully hardened it is the hardest of this family of stainless steels. Hardness is optimised at the expense of other properties. Typical applications...
  • Stainless Steel - Grade 416 (UNS S41600)
    Article - 23 Oct 2001
    416 is the most machinable grade of stainless steel. It is a low cost grade and can be used unhardened, hardened and highly tempered states. Hardness is optimised at the expense of other properties...
  • Stainless Steel - Grade 410 (UNS S41000)
    Article - 23 Oct 2001
    410 is the basic martensitic grade stainless steel. They are optimised for high hardness, although other properties can be compromised. Corrosion resistance is aided by hardening. Typical applicatiosn...

The Current State of the Global Semiconductor Market

The global semiconductor market has entered an exciting period. Demand for chip technology is both driving the industry as well as hindering it, with current chip shortages predicted to last for some time. Current trends will likely shape the future of the industry, which is set to continue to show

How are Graphene Batteries Made?

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
