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 of the classic Lauberhorn slope, on 18 January. Janka competed in his first international FIS race in December 2001 at age 15. Not until four years later did he reach the podium, but success came in all four disciplines. Janka began racing on the FIS European Cup circuit in January 2004. He earned his first two World Cup starts in December 2005, but did not finish either race. At the 2006 Junior World Championships in Mt. Ste. Anne, Quebec, Canada, he won the bronze medal in giant slalom, and he finished the 2007 season in fourth place in the overall
