For each of the 7 “High Performance Materials” you need to know: High Performance Materials: Top Trump Cards For each of the 7 “High Performance Materials” you need to know: Properties Examples of use Reasons for use Improvements on traditional materials The cards can be used for revision, testing each other in pairs, and playing games to help you remember the info High Performance Materials: Ceramics – Boron Carbide Properties: Extremely hard and relatively lightweight Examples of use: Tank Armour, Bulletproof vests, Padlocks Reasons for Use: Very hard, to resist attack or destruction Improvements on traditional materials: Steel is heavier and not as hard. High Performance Materials: Ceramics - Cubic Boron Nitride Properties: Abrasive (wears away other materials), similar structure to diamond Examples of use: Filing/wearing away metals. Tool bits, cutting tools Reasons for Use: Harder than everything else it might have to smooth, or cut (can be used on super alloys) Improvements on traditional materials: Normal Steel files/cutting bits would blunt quickly on hard materials (like super alloys) High Performance Materials: Ceramics – Zirconia Properties: Low cost, Durable, Perfectly clear, Looks like diamond Examples of use: Abrasives, Refractory material (used to bend light/lasers), Decoration, Teeth! (crowns) Reasons for Use: Very hard, Clear and colourless, Can be cut into a diamond shape Improvements on traditional materials: Cheaper than diamond High Performance Materials: Metals - Tungsten Properties: Hard (when made into TUNGSTEN CARBIDE) and Strong EVEN WHEN HOT Examples of use: Lathe Tools, Milling Tools, Light bulb filaments Reasons for Use: Doesn’t get blunt quickly even when HOT and Doesn’t break when HOT Improvements on traditional materials: Steel is not as hard and is too easily softened by heat (unlike Tungsten) High Performance Materials: Metals - Titanium Properties: Light weight, Strong, Ductile (can be made long lengths) Examples of use: Aerospace (Aircraft Landing Gear), BioMedical (hip replacement) Reasons for Use: Light in weight but high strength Improvements on traditional materials: Steel is heavier, Aluminium is not as strong High Performance Materials: Super Alloys – Nickel Based Properties: Light-weight, Strong even at High Temperatures, Corrosion-resistant Examples of use: Aircraft engine parts, Power station turbine parts, Casting Dies Reasons for Use: When spinning at high speed & temperatures it won’t break even if it gets wet Improvements on traditional materials: Stronger than Titanium / Stainless Steel at higher temperatures) (& lighter than steel) High Performance Materials: Super Alloys – Cobalt Based Properties: Lightweight & Corrosion resistant Strong at EXTREMELY high temperatures Examples of use: High Temperature Turbine parts (aerospace/power stations) Reasons for Use: When spinning at high speed & EXTREME temperatures it won’t break even if it gets wet Improvements on traditional materials: Stronger than Titanium (& even Nickel-based Superalloys)even at EXTREME temperatures
