Hi Guys,Without getting at all technical...............no major company seeking to maximise their profit margin is going to adopt a process which is not going to give a positive benefit, be it buying a field, producing parts 5 years in advance of them being required; etc.For the technically minded.http://www1.eere.energy.gov/manufacturing/resources/metalcasting/pdfs/age_strengthening.pdfBest RegardsBob
I have been told that the carbon will precipitate and be dispersed in solution over time.
Trim>The carbon lowers the melting temperature, that's a wanted property. <trim
The Iron Carbon phase diagram seems to contradict that statement.
QuoteThe Iron Carbon phase diagram seems to contradict that statement.Not that much.Not so much, because carbon steels stops at 2.06% of carbon. Not so much, because the diagram is misleading. Right of the eutectic, the solid line going upwards is NOT where you have molten metal. The dashed line that stops at 1253 °C and the solid horizontal line is liquid too."L + C(graphite) is liquid plus primary Fe3C.The section (roughly) lined out by 0.16, 2.1 and 4.2 is liquid too (liquid + gamma-mc (mixed crystals)).So above 2.06 % C, you have won and a constant melting temperature of 1153 °C.Nick
