The results showed the accuracy of this equation with respect to the theoretical one. Afterwards, the measured values of Rockwell hardness (HRF) and Vickers hardness (HV) were related to each other by a simple equation according to theory.
Moreover, the relationship derived from ASTM standards and Hollomon parameters were calculated from the engineering stress-strain curves. Firstly, the pre-existing relationships were considered and verified for AlSi10Mg SLMed alloy. Relationships between hardness and yield and ultimate tensile strengths have been calculated by combining Hollo-mon parameters (the strain hardening exponent 'n' and the strength coefficient 'K') for the Selective Laser Melted Al-10SiMg alloy. The problem of finding meaningful relationships between hardness and tensile strength has been addressed for materials produced by additive manufacturing technology. I also focus on the connections between photography, death and haunting which the Portfolio seems to invite, as well as on the larger dialogic potential contained within a visual narrative set in a small NYC underground community in the 80s, and which is undoubtedly both an autobiographical account (in the sense that by documenting Mueller, Goldin inevitably documents herself) and a memorial to a memorialist (Cookie herself wrote mostly autobiographical fictions, most of which are out of print now).Selective Laser Melted Al10SiMg samples were directly aged at different temperatures and times to establish the best mechanical properties for this alloy. I start by addressing the larger issue of how the representation of the AIDS crisis was transformed by the documentary endeavor of a photographer who was both subject and object of the gaze in an archival project constructed as a gesture of anticipated mourning. This chapter examines Nan Goldin’s Cookie Portfolio, the well-known series of photographs of her good friend Cookie Mueller from the beginning of their relationship (1976) until Mueller’s death (1989), in order to answer several questions about visuality, autobiography, marginality and death.
