Factors Affecting Ductility & Brittleness. Several factors can affect the ductility and brittleness of a material, including: Temperature: As mentioned earlier, temperature plays a crucial role in determining the ductility and brittleness of a material. At high temperatures, materials are typically more ductile, while at low temperatures, they tend to become more brittle.Abstract. An improved low-temperature brittleness tester, capable of testing five specimens simultaneously, is described. All machine specifications conform to A.S.T.M. Method D 746-44T. Data are presented which show that many elastomers do not possess a sharp brittle point but are characterized by a distribution of failures over a temperature interval. The improved .
