Hardness of dislocations, a particular metal's hardness can be controlled. Although seemingly counter-intuitive, as the density of dislocations increases, there are more intersections created and consequently more anchor points. Similarly, as more interstitial atoms are added, more pinning points that impede the movements of dislocations are formed. As a result, the more anchor points added, the harder the material will become. Hardness Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Some materials (e.g. metals) are harder than others (e.g. plastics, wood). Macroscopic hardness is generally characterized by strong intermolecular bonds, but
Carlo Janka Cup overall title. He clinched the title by winning the downhill and giant slalom, which left his nearest opponent, Benjamin Raich, 106 points back with one race remaining, an insurmountable margin. In October 2010, Janka was awarded the Skieur d'Or Award by members of the International Association of Ski Journalists for his performances during the previous season, thereby becoming the first Swiss male skier to receive the honour since Pirmin Zurbriggen won it back in 1990. Following the 2011 World Championships, Janka underwent surgery due to increased symptoms from heart arrhythmias. A radio frequency catheter intervention was done on 23
