Oak Ridge National Laboratory has partnered with FCA US LLC and casting manufacturer Nemak to develop a new cast aluminum alloy for engine cylinder heads, which could lead to more fuel-efficient internal combustion engines.
Scientists at Oak Ridge National Laboratory have conducted a series of breakthrough experimental and computational studies that cast doubt on a 40-year-old theory describing how polymers in plastic materials behave during processing.
