Porous metals and metallic foams are composite materials in which one phase is gaseous and another phase is solid metal. The mechanical behavior of these materials depends mainly on the mechanical properties of the solid metallic phase, the structural configuration of the solid and the density of the composite ρc, relative to the density of the solid phase ρs. The primary distinction between a porous metal and metallic foam is the relative density, metal gas composites with a relative density (ρc/ρs) above 0.3 are generally considered porous materials, while those with a relative density below 0.3 are generally considered to …


Review On The Suitability Of Conceptual Performance Measurement Systems For Lean Manufacturing, Dilanthi M. G.S Oct 2015

Review On The Suitability Of Conceptual Performance Measurement Systems For Lean Manufacturing, Dilanthi M. G.S

Innovative Research Publications IRP India

Lean manufacturing is implemented to improve any organizational performance so that its performance should be measured to assure the organizational goal attainment. But the past studies have not yet suggested any specific performance measurement system for lean manufacturing. Therefore this paper reviews the conceptual performance measurement systems and their suitability to measure the lean performance and hence argues that a new performance measurement framework should be developed.


Responses Of Ka’Oje Metallurgical Manganese Ore To Gravity Concentration Techniques, R. A. Muriana Jul 2015

Responses Of Ka’Oje Metallurgical Manganese Ore To Gravity Concentration Techniques, R. A. Muriana

Innovative Research Publications IRP India

Metallurgical manganese ore samples from Ka’oje (Nigeria) were enriched to higher Metallurgical grades during wet gravity separation techniques which included Jigging and Tabling operations. As-mined samples S1 (36.83%MnO), S2 (47.85%MnO), S3 (58.85%MnO) and S4 (54.96%MnO) were dressed and screened to -780+500 μm, -500+355μm, -355+250 μm, -250+192 μm and -192 μm particle size ranges. Obtained Jigging test concentrates assayed 51.54% MnO minimum recovery level with an enrichment ratio (ER) of 1.02; while Tabling operation concentrates assayed 91.11% MnO maximum recovery and 1.14 ER value. These responses demonstrated the suitability of the two techniques in raising the enrichment levels of the ores …

Design & Analysis Of Ø40” X 80” Conventional Sugar Mill Head Stock., Santosh Y. Salunkhe

Innovative Research Publications IRP India

Sugar mill head stock play a significant role in the sugar plant as they have to sustain the forces experienced by the rollers while extracting juice from the cane. The present analysis related to modification in sugar mill head stock Ø40”X80”. This paper describes the advantages of using Ø40”X80” mill head stocks by designing & analysis by ANSYS software. In this study theoretical study has been done considering the Bending moment & force polygon diagrams. Bending moment factor which helps in finding actual results. By changing various parameters the performance of mill head stocks is studies using static structural analysis …


Effects Of Heat-Treatments On Tensile Strength And Electrical Conductivity Of Locally Formulated Al-Ni Alloys, R. A. Muriana, O. K. Abubakre, S. B. Tajiri Jul 2015

Effects Of Heat-Treatments On Tensile Strength And Electrical Conductivity Of Locally Formulated Al-Ni Alloys, R. A. Muriana, O. K. Abubakre, S. B. Tajiri

Innovative Research Publications IRP India

This Paper investigated effects of annealing and age hardening on the ultimate tensile strength (UTS) and electrical conductivity of aluminium-nickel cast using sand mould. Pure aluminium melt was alloyed with nickel, which was added in 2% to 10% step 2. Annealing and age hardenings were carried out and obtained results showed that Al-2%Ni alloy has the highest UTS of 604.44MPa. On the other hand, Al-6%Ni Annealed alloy has the highest electrical conductivity, with a value of 6.15 × 107 S/m. The Al-4%Ni alloy combined both high strength and conductivity, having UTS of 603.28MPa and electrical conductivity of 5.69 × 107 …
